WHEELED CULTIVATOR.

Application filed March 15, 1928. Serial No. 281,872.

lhe present invention relates to a wheeled cultivator and has for its prime object to provide an improved frame structure for niountin g cultivating and harrow implements in an adjustable manner.

Another very important object oi the in' veution resides in the provision of an apparatus ol this nature which is simple in its con struction, strong and durable, inexpensive to manufacture, thoroughly efllcient and reliable in use, and otherwise well adapted to the for which itis designed.

lVith the above and numerous other objects in View as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

in the orawing:

Figure 1 is a top plan View of the apparatus embodying the features of my invention,

l igure 2 is an elevational view thereof,

Figure 3 is a traginentaryperspective View of: one of the cultivator beams with a shovel and shank attached thereto, and

Figure l is a fragmentary perspective view of one of the rake bars showing one of the barrow teeth attached thereto.

Referring to the drawing in detail it will be seen that the numeral 5 denotes an arch on the ds of which are journaled wheels 6.

A ti-shapes frame member 7 has its ends secured 1 ends oi lhcrclroui. A brace S is secured to the center of the li-lgght portion of the spring, member 7 .7 in auysuitable manner to the rOIl'iT-I) thecenter ot the top cross bar ot arch :1 d extends rearwardly therefrom. nountcd on a support 10 which ed to an intermediate portion hcliue l part of the brace 8. [in arm iroiects 'ardly from the centcrot the big 1t ot the :raine n'iember 7 and has dirigibly mo uited. inc-rein a for ard wheeled truck structure which has suitable means 145 ascl l therefrom which may be hitched the draft such tractor, horses or the like.

A plurality 01" beams ers hin'gedly connccten as 16 with the bight portion of th; and extend rearwardly and tr e n'ien'iher have their rear ends curved downwardly as at 17. o are a'lgustably connected r A. xfiJtliluda LU with the ends 17 by pin and slot connect1ons the arch 5 and projects forwardly.

inclines uprurdly and rearwardly and.

19 for suitable adj ustinent "and spear pointed is 5 30 are attached to thel lower end or he shanks it. A bar is extended trans- 5 the apparati'ls bcingattached to rn'icdiate portions of the beams 15. urality of beams 15 are attachedto the sat one hetwecn'cach pair I crossbar c- W ctbeanis ll.

e beams 15 are similarly constructed lXhlllS 15' exceptthat they are 'inuch l spear point plows 20 which shorter and toe are-engaged therewith are disposed forwarch ly of the first mentioned Braces 23 are engaged with the bars 21 at the point i ZfZand diverge forwardly to be engaged spear point shovels.

with the forward end portions of the beams 15 as is clea v indicated in Figure 1, Thus the strong and rigid frame structure is orovided. Links 24 are engaged with the rear end portions of two of the beams 15 adjacent the sides or the apparatus and levers. L5 are rockable onthe top cross bar of the arch 5 and engaged with the link tor raisin and lowering the shovels 20 as a unit. I

Notched quadrants 25 are n'muntod on the. arch and dogs 27ers mounted on the lovers 25 for engagement therewith so that the shovels 2O nu he held in h 'erent adjusted posi tions. rein the n'ientioned beanie 5 there extends rearwardly arms 30 which are pivotally engaged Wl'tfl. s id beams as at 31 and extendover the top of a cross bar 32 which attached to the rear end of the beams 15 A. pair of trcnwerscly extending; space( l"- the bean 33 so that they maybe rocked to vary the angles ofthe teeth 84: with respect to the groinid may be desired.

iluitshle beams 87 are associated with each lc er 38 so as to hold the same in the desired position. it is thought that the Lion. operation, and advantages oi s invention will now be quite apparent to those skilled in this art without a more dedescription thereof.

. In actual practice I have found this apparatus very elllcient in eliminating; Weeds, morning glories and the like. The apparatus lllll works to advantage with hard ground that T i cannot be suliiciently plowed with a. disk.

The apparatus loosens the soil and maintains the ground level. The apparatus may be i used at any depth desired.

lhe present embodiment of the invention has been disclosed in detail merely by Way of example since in actual practice it attainsthe features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, \vnat I claim as new is:

A ground working apparatus of the class described comprising a Wheeled arch, a U- shaped frame extending rigidly and forward ly from the ends of the arch to have its bight disposed forwardly, a plurality of beams, means for hingedly mounting the beams on said bight, a bar extending across the intermediate portion of the beams, other beams engaged on said bar and extending between the first mentioned beams, the rear ends of said beams extending downwardly, shovels, means for attaching the shovels to the rear ends of the beams,and means for raising and lowering the beams as a unit, arms pivotally engaged with some of the first mentioned beams and extending rearwardly therefrom, a bar connecting the rear end of the first mentioned beams over which said arms extend, a pair of spaced parallel transversely extending beams, means forrockably mounting the last mentioned beams on the arms, teeth projecting from the last mentioned beams, and means for rocking said last mentioned beams.

In testimon' whereof I aim-'1 m si 'nature. b
